Maksim Krasnyanskiy:
o [Bluetooth] Add support for FCon and FCoff flow control commands
o [Bluetooth] Credit based flow control (CFC) must be disabled by default for compatibility with 1.0b devices. Made CFC a session attribute, introduced CFC states and cleaned up CFC logic.

Trond Myklebust:
o Fix a deadlock in the NFS asynchronous write code
o A request cannot be used as part of the RTO estimation if it gets resent since you don't know whether the server is replying to the first or the second transmission. However we're currently setting the cutoff point to be the timeout of the first transmission.
o UDP round trip timer fix. Modify Karn's algorithm so that we inherit timeouts from previous requests.
o Increase the minimum RTO timer value to 1/10 second. This is more in line with what is done for TCP.
o Fix a stack overflow problem that was noticed by Jeff Garzik by removing some unused readdirplus cruft.
o Make the client act correctly if the RPC server's asserts that it does not support a given program, version or procedure call.
